6 Energy saving tips 4.7 Displays Special Description display Venting function enabled (approx. 2 minutes). 5 Energy saving tips Summer mode (appliance frost protection) e.g. EA Fault code ( chapter 6) only Standby Table 3 Economy mode The appliance is designed in such a way that gas consumption and environmental pollution is kept to a minimum and comfort is as high as possible. The supply of gas to the burner is regulated in accordance with the home's heat demand. If the heat demand is low, the appliance continues to operate with a small flame. The contractor refers to this process as continuous control. As a result of continuous control, temperature fluctuations are kept low and heat is distributed evenly in the rooms. This may mean that the appliance is in operation for a longer period of time but actually consumes less gas than an appliance that is constantly being switched on and off. Inspection/Maintenance To ensure that gas consumption and environmental impact (pollution, etc.) remain as low as possible over an extended period of time, we recommend that you take out an inspection/maintenance contract with an authorised installer covering the annual inspection and servicing and maintenance at other times as required. Thermostatic valves Fully open the thermostatic radiator valves in order to achieve the required room temperature. You can only change the required room temperature at the controller when the temperature is not reached after an extended period of time. Venting Do not leave windows open for ventilation purposes as this will allow heat to be discharged from the room without significantly improving the air quality. It is preferable to fully open the windows for a short period of time to air the room completely and then shut them again to maintain temperature. Circulation pump If there is a circulation pump for hot water, use a timer programme to control its operation according to the specific requirements (e.g. morning, afternoon, evening). 6 Troubleshooting All safety, modulation and control components are monitored by the Heatronic system. If a fault occurs during operation, the display shows the symbol and possibly, and a fault code (e.g. EA) flashes. If and appear: Press and hold down until the and symbols are no longer displayed. The appliance will start up again and the flow temperature will be displayed. If only appears: Switch the appliance first off and then on again by means of the standby key. The appliance will start up again and the flow temperature will be displayed. If a fault persists: Contact your approved installer or Customer Service for assistance, providing details of the fault and the appliance. For service and maintenance issues please contact the following numbers: Australia :1300 30 70 37. New Zealand :0800 54 33 52.
